Patent GB-552684-A (GB)
Title: Improvements in or relating to the production of gaseous olefines
IPC: C07C4/04
Filed: 1941-10-27
Abstract: 552,684. Gas manufacture. DISTILLERS CO., Ltd., and WOOD, W. L. Oct. 27, 1941, No. 13798. [Class 55 (ii)] Gaseous olefines are produced by bringing a gaseous or liquid hydrocarbon into contact with a previously heated mass of refractory material and, as the material cools, increasing the contact time by varying the concentration and/or rate of admission of the hydrocarbon to maintain an optimum contact time at each temperature to obtain a maximum yield of olefines. An inert diluent such as steam or distillation gas may be used in varying amounts. When the gases or vapours obtained have a density of .95 with reference to air, the maximum olefine production is achieved, thus the condition of working is controlled in accordance with the density of the effluent gases. In an example, gas oil is used with steam as a diluent, the material being at 800‹ C., the steam being reduced as the temperature fell to 700‹ C.

Title: Seiko koki kk exposure delay mechanism for camera shutter
IPC: G03B9/64
Filed: 1974-03-29
Abstract: 1469836 Camera shutters SEIKO KOKI KK 29 March 1974 [31 March 1973] 14068/74 Heading G2A A mechanism for delaying shutter opening comprises a rotary member 18 which is set by manual anti-clockwise rotation to the position shown in Fig. 2 so as to return when released under the action of the spring 20 and a governer mechanism. The invention lies in the fact that as the rotary member is set it gives a small anti-clockwise shift to a control lever 22 pivoted on a sliding plate 10 which is held against upward motion, produced by spring 25, by engagement of a shoulder of the lever 22 beneath a fixed stop 12a. Moreover, such displacement of the lever 22 frees the shoulder from the stop and lets the plate 10 rise to the position shown in Fig. 2 where the vertical face of the shoulder lies against the side of stop 12a. Furthermore, in this position the control lever 22 has shifted anti-clockwise a brake lever 27 a lug 27a of which runs in a slot 22c of the lever 22. When so shifted the brake holds the speed governer to prevent the rotary member 18 returning from its set position. Setting of the rotary member 18 also displaces a locking lever 28, pivoted on the fixed frame of the mechanism, so that a hooked upper end 28a underlies a pin 6b on a spring-biased detent 6 pivoted on the manually operable shutter release plate 2. On shutter release, the plate 2 descends under manual pressure and the pin 6b engages the top of the hook 28a to be deflected and caught beneath it. The hook 28a holds the plate 2 in its depressed position and also holds the upper portion 6a of the detent out of the way of the shutter release lever 7. A projection 2a on the plate 2 engages the plate 10 and forces it down so that a flange 10a on the plate almost operates the shutter release lever 7. Such lowering of the plate 10 moves the shoulder of the control lever below the stop 12a so that the lever is free to move clockwise and in so doing release the brake on the governor while putting its hooked lower end 22a in the path of a pin 18d on the rotary member 18. After the rotary member has turned back clockwise at the controlled speed for a given time the pin 18d engages the hooked end 22b to pull the plate down that extra distance needed to operate the shutter release 7. Further clockwise rotation of 18 frees the hook 22a and the locking lever 28 so that the shutter release plate 2 rises to its original place and the plate 10 rises to its normal position in which the shoulder of the control lever 22 engages beneath stop 12a. When delayed shutter opening is not wanted the rotary member is not set and the locking lever 28 stays out of the way of the detent 6 so that the detent directly engages the shutter release 7 when the plate 2 is manually depressed. During this operation the plate 10 moves up and down with the plate 2 but its motion is idle.
